What you might be wondering
Can I cancel after ordering ?
Yes, as long as production has not started (24h after purchase). A message through the contact form with your order number is enough.
Does the −10% subscription tie me in ?
No commitment at all. You change your formula at every renewal, and you pause or cancel in 1 click from your account area.
What if the formula is not right for me ?
We help you get it right from the start: begin at "Mild" intensity, then the AI Coach fine-tunes your next formula for free. Tub damaged or not as ordered? We replace it or refund it at our expense (legal guarantee). Note: a made-to-measure formula does not give a right to the 14-day cooling-off period (art. L221-28).

A formula built on 4 performance pillars
Every ingredient has a job: energy, focus, pump, strength or endurance.

The pillar you feel first. Three reference actives: anhydrous caffeine, L-theanine, L-tyrosine.

Muscle pump
More muscle volume and better blood flow during the effort — the "pumped up" effect.
- Pure L-Citrulline
- Glycerol
- Himalayan Pink Salt
Pillar 03
Strength & Endurance
Strength, power and muscular endurance. Delays the burn during the effort.
- Beta-Alanine
- Creatine Monohydrate

hidden doses. You see it all.
Zero hiding places. You see EVERYTHING.
The "proprietary blend" is a catch-all total that hides the real doses — very handy for masking underdosing. Here, every milligram is shown.
The "proprietary blend" is a common practice in this market.
8g
the citrulline dose that was studied
8 g of citrulline. The real dose, not the decoration.
The dose from the reference meta-analysis. Plenty of brands settle for 4 g "to look good" on the label. You go up to the dose that counts.

200mg
of caffeine max per portion
Capped at the ANSES limit.
Some US pre-workouts throw in 300-400 mg per serving, outside European standards. Here, the slider is locked at 200 mg — the ANSES limit, full stop.

The studies behind our doses
All our dosage ranges are calibrated on peer-reviewed scientific publications. Here are the 4 main ones.
Caffeine · Mental Drive
21 studies: strength and endurance performance
Caffeine is one of the most studied actives in a sporting context (e.g. the Grgic 2020 meta-analysis, 21 studies). Scientific information presented on a factual basis — no health claim is made for caffeine (EFSA/ANSES regulations).
Citrulline · Muscle Pump
12 studies: reps to failure & pump
According to a meta-analysis of 12 studies (Trexler 2019, European Journal of Sport Science): citrulline (≈8 g) supports performance on repeated sets to failure and perceived muscle recovery after the effort (a pump effect from 4g through nitric oxide vasodilation).
Beta-Alanine · Power & Stamina
40 studies: performance over 1-4 minutes
According to a meta-analysis of 40 studies (Saunders 2017, BJSM): Beta-Alanine 4-6g/day x4 weeks improves performance on efforts of 1-4 minutes through muscle carnosine saturation (pH buffer). Tingling (paraesthesia) is normal, temporary and reversible.
L-Theanine + Caffeine · Mental
Focus synergy & anti-jitters
According to the Kahathuduwa 2017 study (Nutritional Neuroscience): L-Theanine 200mg + Caffeine 160mg supports attentional accuracy and reduces perceived mental fatigue versus caffeine alone.

The first pillar you feel when you start: caffeine, L-theanine and L-tyrosine, adjustable to the milligram to suit you.
The muscle pump: more blood flow to the muscles for that "pump" feeling during the effort.
Power and explosiveness: for short, intense efforts — lifting heavy, starting hard.
Go the distance: delay muscular fatigue and hold hydration through long efforts.
Do you want creatine in your formula?
Switch it on to add it to your formula — the dose follows the Strength pillar (up to 3 g). Leave it off if you already take it separately.
